Most Helpful Positive Review FAB Defense GL Shock
Well made. Some people mentioned having to bang the stock on the floor to do the installation. If you take your time , the stock will slide over the detent without using a lot of force. Nice snug fit. Good ergonomics. FAB Defense makes some nice equipment. Shipping as always was great. Customer serv...

Most Helpful Negative Review Does not fir correctly on the buffer tube!
Inside diameter of butt stock is larger than that of my mil-spec- buffer tube, hence it "wobbles" when installed! I previously have had a Mag-pul and a Hogue butt stock on this same rifle with no issues regarding fit, so I know that my buffer tube is the correct size! Therefore, I cannot recommend t...

Originally To Tight To Completely Slide Up And Down Buffer Tube.

by Sam, Verified Owner from NC, United States Written on November 8, 2025
I purchased this to go on my Daniel Defense with a Milspec buffer tube. The stock fiy on the buffer, but would not slide all the way up the tube. It became in a bind a little more than half way up the tube. It also performed the same way on my LWRCI. I was originally going to send it back, but after looking in the back side of the tube, I figured out where it was binding. I took a small file and worked with it, as well as using some dry silicone spray to get it fixed. I now use it with no issues at all. It seems as if FAB Defense would do a better job on production, but I guess there is one lemon in every basket. Only 2 Stars because I really had to work with it to get it to work as intended. But if you are not afraid to fix it, yes I would recommend it. It is a great stock, and I plan on getting another for my LWRCI. But I am gonna keep the file handy!
Pros:
  • Great Stock. Very Rugged And Adjustable
Cons:
  • Poor Quality Control On Original Production
Best Used for:
  • AR15
Would recommend: Yes

…not so “FAB”…

by Shademan, Verified Owner from PA, United States Written on March 7, 2025
I realize that any AR furniture is a matter of personal preference and often times it will always be function over form. However, this stock is the most uncomfortable AR part I have ever owned. First, the plastic edges are hard and unfinished. Caught my finger on one and have a nice reminder of the experience. The arm cushion needs a lot of help to be comfortable. Finally, the cheek rest is not high enough to focus on a rifle scope. The upside…it looks great.
Pros:
  • looks are very nice
Cons:
  • as comfortable as a cynder block
Would recommend: No

Isreali’s strike again

by HAMbo, from KY, United States Written on August 31, 2022
Had absolutely no issues with this stock, all my friends that have shot my AR love it as well. Recoil system works great, I also not the slide in mono pod shoulder piece and it’s all awesome. No complaints whatsoever and couldn’t imagine having any other stock on my gun. Somethings not right about the guns that people are saying it didn’t fit well on. Fits flawlessly on my Springfield Saint Edge perfectly.
Would recommend: Yes

Nice stock, a little losr

by Fred, from NC, United States Written on May 6, 2021
I purchased this a few days ago. Got here in 2 days, instantly put it on my rifle. It was a little hard to get on, but once I figured it out is was simple. Instead of pushing the tap down like you would yo adjust it, go to the other end of the tap and pull in toward you while pushing it onto the buffer tube. It will allow it to clear onto the tube correctly. (Takes a little bit of strength.) Only thing I can say bad about it is I feel it would fit a commercial buffer tube better, it is a little lose on my mil spec tube. The stock itself is well built, sturdy feeling and has a satisfying heft. Very very good shoulder feel, and the recoil reduction system does work nice.
Pros:
  • Sturdy, works as advertised.
Cons:
  • Loose fit on mil spec buffer tube
Would recommend: Yes

really impressed.

by Wes Dempsey, Verified Owner from UT, United States Written on February 11, 2021
First things first. I need to correct something. The idiot who gave this piece a bad review for poor functionality and a dated look is a complete numbskull. He obviosly doesnt know what most of the functions are and how the corporate with the function of your rifles. The cheek piece is amazing for my reflex sight that sit on top of my scope. Second. It is also slimmed and rounded to allow access to you charging handle while in the up position. For longer shots with my scope i charge back the riffle then lower my cheek piece before chambering and firing. The recoil spring is amazing. I unloaded a full mag and stayed in body with 4in horizontal group at 40 yards. Super easy to control. I will have one of these on all my builds. Oh yeah. Plus you can remove the cheek piece for a sleeker look and feel but why. Get one you wont be sorry

Where is the built in recoil-reducing mechanism

by Scott, from WA, United States Written on February 21, 2019
For the cost of this stock you would think it would actually be what it says it is. There is no recoil-reducing mechanism with a premium silicon chrome alloy spring. Just a very sloppy fitting composite stock with a rubber buttpad cushion. It may look nice - but definitely not worth the money. Will be sending this thing back.
Pros:
  • Looks
Cons:
  • Not what it says it is, cheap and sloppy
Best Used for:
  • Returning and buying a good stock
Would recommend: No
